Another Republican is accusing President Obama of secretly being a Kenyan man who forged his birth certificate in order to get elected President of the United States. This time the theorist is Rep. Jeff Duncan (R-SC), chairman of the House Homeland Security Oversight Subcommittee.

Duncan appeared on the radio program TruNews with Rick Wiles on Friday where the host asked the South Carolina congressman whether the House would go after Obama’s “phony identification papers.” Duncan initially demurred, but then agreed with Wiles that Obama could be lying about his birth certificate, calling for Congress to “revisit” the issue of “the president’s validity.”

WILES: While you guys are rounding up and deporting the illegal immigrants, any chance the House may actually pursue President Barack Obama’s phony identification papers? That’s the original scandal, congressman.

DUNCAN: People should have voted against him in November. I’m afraid that that wouldn’t get to the Supreme Court where it ought to get.

WILES: But if we know they’re lying about all these other things, why not go back and say, “well maybe the first scandal was a lie, too?”

DUNCAN: There you go. I’m all with you. Let’s go back and revisit some of these things because Americans have questions about not only the IRS scandal but also about the president’s validity.

At this point, the birther conspiracy is so thoroughly de-bunked that Republicans could accuse President Obama of secretly being a Snorlax and it would be no less credible than accusing him of being a modern-day Manchurian candidate.

In his three years in Congress, Duncan has developed a reputation for controversial statements. He has invoked other conspiracy theories peddled on websites like the Drudge Report, falsely claimed that he didn’t vote to extend big oil subsidies, and warned that background checks will lead to Rwandan-like genocide in the United States.
